Create a Shortcut on the Startscreen of your device using the CreateShortcut method of the app object:
app.CreateShortcut(name, picturepath, scriptpath)
You can start a Scriptfile with just one click within Droidscript.
function OnStart() { app.CreateShortcut( "Hello World", "/mnt/sdcard/DroidScript/Hello World/Img/Hello World.png", "/mnt/sdcard/DroidScript/Hello World/Hello World.js" ); }
